FILM DISPENSER Filed July 25, 1955 IN VEN TOR. MOW/am 6. Jon asATTORNEYS William C. Jones,

Chemical Company, Midland, Delaware Application July 25, 1955, SerialNo. 524,006 3 Claims. (Cl. 312-39) Mich., a corporation of Thisinvention relates to a film or tape dispenser and particularly to animproved dispenser for limp, clinging films which carry a considerablestatic electrical charge.

Conventionally, the cutting edge is fixedly secured to an edge of thedispenser box. Such dispensers are less satisfactory than is desiredwhen used to dispense limp, clinging films which carry a considerablestatic electrical charge.

When thin, clinging films which are made of vinylidene chloridecopolymers (such as are sold under the trade a principal object of thisinvention is to provide an improved dispenser for limp, clinging filmswhich is positive acting, and which, when used, provides a clean-cutedge on the panying drawings, in which:

Fig. 1 is a top plan view, partly broken away, of a film dispenser madein accordance with this invention and including a roll of film in thedispenser;

Fig. 2 is an elevational View of the front of the dispenser shown inFig. 1;

Fig. 3 is an end elevational view of the dispenser shown in Fig. 1, and

Fig. 4 is a sectional view taken along the line 44 of Fig. 1.

Referring to Figs. 1, 2, and 3, there is shown a film dispenser,indicated a sheet-like back panel 12,

for enclosing the ends of the dispenser 10.

The cover 18 is hinged to the end panels 20, 22, as by the rivets 24,near the top rear part of the dispenser. The cover 18 extends from therear of the dispenser approximately percent of the distance to the upperfrontedge 26 of the body of the dispenser 10.

A cutter blade, indicated generally by the numeral 28, which extendsalong substantially the entire length of the dispenser 10, is hinged,for example, at 30 near the top of each of the end panels 20, 22 andsomewhat forward of the edge 32 of the cover 18.

Referring also to Fig. 4, the cutter blade 28 has an upper section 34 ofgenerally arcuate cross section which cutting edge 36, which isillustrated 30 of the blade 28. 34 exceeds the area of film 38 whichmust be un-rolled from the dispensing roll 40 as the roll 40 drops toThe upper blade section 34 of arcuate cross section has a slightlyroughened or satin finish l4-15 microfinish, for example) which ishelpful in preventing excessive sticking of the film to the blade.Aluminum blades are advantageous because of their low cost and becauseof their natural satin finish. The edge 32 of the cover 18 isillustrated as being removed from the upper section 34 of the blade 28in order to provide a better grasping area by which film may be removedfrom the dispenser 10.

However, if desired, the edge 32 of the cover 13 could extend to theblade tearing edge 36 of the blade 28. The cover dispenser is thenclosed.

To remove and tear film 38 from the roll 40, the film 18 of the may beevenly torn along the serrated cutting edge 36 of the blade 28 as a onehanded operation.

The roll 40 may rise slightly from the bottom 14 of withdrawn therefrom.cling tendency of that part of the film 38 he upper section 34 of thefilm 38 from dispenser as: the roll dispenser 10. The dispenser box maybe fabricated either of metal, polystyrene, or other Similarly of hingorof pivoting the blade, for

exam le may be changed as long as the described relations'hip betweenthe blade, roll, and stop means is maintained.

I claim:

1. Apparatus for dispensing and severing sections of sheet materialhaving a considerable static electrical charge from a roll of such sheetmaterial contained within the apparatus, comprising a box-like containerdimensioned to hold therein a roll of said sheet material, saidcontainer comprising front, back, end, and bottom panels and a top coverhaving a front part and a bacl; part, said top cover being hingedadjacent to said back part to at least one of said panels, said coverextending a major part of the distance between the back and front of thecontainer, a pivoted cutter blade for severing film material, said bladebeing attached to the ends of said conminer and having an upper sectionwhich extends across said container and projects over the upper edge ofthe frontpanel, said upper section having a cutting edge, a lower bladesection adapted to bear against said roll in line contact therewith, andan offset blade section joining said upper section and said lower bladesection, said offset section being out of the path of said sheetmaterial as it is dispensed or torn from the roll.

2. Apparatus in accordance with claim 1, wherein said cutter blade is sopivoted that the lower blade section lies free of said roll except whenthe upper section is moved downwardly.

3. Apparatus in accordance with claim 1, wherein said cutter blade ismade of aluminum.
